Johnson & Johnson heiress Casey Johnson was infamous for her last name and her wild lifestyle.
She passed away at the age of 30 shortly after the New Year and the media started to speculate that drugs were the cause of death.
Her toxicology reports are finally in and according to the L.A. Coroner, she died of "natural causes."
The specific cause of death was "diabetic ketoacidosis," a condition caused by a shortage of insulin, according to a coroner statement via People magazine.
She simply wasn't taking care of herself. She was not taking her insulin shots, was not exercising, and didn’t follow a healthy diet kept skipping crucial medications that were needed to keep her diabetes under control.
Johnson had suffered from severe diabetes since childhood, which prompted her family to set up the Juvenile Diabetes Research Foundation.
Johnson left behind her adopted daughter, Ava, 3, who will live with Casey's mother Sale "for the foreseeable future," according to a family source.
As tragic as her passing was, we're glad to hear drugs were not a factor in her death. We've already lost too many people to overdoses!
